SPECIFICATION forming part of Letters Patent No. 322,794, dated July 21,1885. Application filed December 9, 1384. (No model.) I

To all whom it may concern.-

Be it known that we, JOHN W. CLOUD, a citizen of the United States,residing in the city of Altoona, in the county of Blair and State ofPennsylvania, and AXEL VOGT, a subject of the King of Sweden, butresiding in said city of Altoona, have invented certain new and usefulImprovements in Motors, of which the following is a specification.

Our invention is specially intended for use in industries requiringlittle power, sometimes designated as the small industries, and itrelatesto ainachine the movementof which is produced by the pressure ofa fluid and by the action of gravity exerted upon parts of the machine,as hereinafter specified.

In carrying out our inventionwe use a casing or wheel, inclosingcylinders, to the piston of each of which isatt-ached a weight freetomove with said piston relatively to the casing or wheel, all beingmounted so as to be free to rotate together. 'We also use a valve soconstructed and arranged that the rotation of the casing or wheel andits adjuncts will bring certain ports into such relative position as toproperly admit the fluid to one cylinder to lift its piston and attachedweight, and to allow fluid to escape from the other cylinder to theatmosphere, the whole being so timed as to cause the casing or wheel torevolve by the action of gravity when the center of gravity of the wholemass is at one side of the vertical plane through the axial shaft. \Vedo not restrict ourselves to the number of cylinders and their adjuncts.One cylinder only may be used with a suitable valve, or any suitablenumber of cylinders. Neither is .it essential to our invention that onlyone valve be used, as a separate valve for each cylinder may beemployed. 7

In the accompanying drawings, Figure 1 is an exterior side elevation ofour invention. Fig. 2 is a vertical transverse section. Fig. 3 is avertical longitudinal section.

Similar letters of reference indicate similar parts in the respectivefigures.

A is a cylindrically-shaped casing or wheel, free to revolve upon itsaxial shaft a, which is mounted in bearings B, provided therefor. Thecasing A is formed in any suitable manner. Preferably one side, b, ofthe casing is cast integrally with the shaft a and adjacent part b, theother side, I), being bolted to the part b. To the parts I) and b of thecasing one ormore cylinders, G, are attached, each being provided with apiston, c. The cylinders are preferably cast solid with the said parts.A weight, D, a side elevation of which is shown in Fig. 2, attaches tothe end of each piston by means of screw-bolts f. The shape in outlineof the weight is less than that of a true circle, being that of twounited arcs of a circle each having a radius equal to that of theinterior of the casing A, each arc being less than a semicircle, theconstruction being such that when the weight rests within the casing, asshown in Fig. 2, a lune-shaped space, 0, is left. The center of theweight is cut out or slotted, as shown in Fig. 2, at 0, so as to allowit to slide over or upon the cylinders O.

The shaft a is hollow or tubular, and through it passes longitudinallythe valve 9, which is also tubular. The valve is adj ustably attachedthrough the medium of the slotted lug h and bolt h, to a bearing, h",secured to a fixed part of the motor. The valve 9, when so secured, isincapable of rotation, The valve is provided at its longitudinal centerwith an inclined partition-plate, c, an upper supplyport, 6, and a lowerexhaust-port, i. The supply-port t" is adapted to have communication, atthe proper time for the admission of fluid to the. cylinder occupyingthe upper position, with a port, 70, formed in the inner head of saidcylinder, while the exhaust-port t is in communication with the port kof the other cylinder.

' Supposing the position of .the portsto be as indicated in Figs. 2 and3, the fluid is admitted under pressure through the valve 9 to the undersideof the piston of the upper cylinder, causing it to rise, and to liftwith-it the piston of the lower cylinder and the weight D. It will beobserved that during the time the port 41 of the valve is incommunication with the port k of the upper cylinder the eXhaustport 45of the valve is opposite the port k of the lower cylinder, permittingthe fluid to escape from this cylinder. The weight D having been shiftedfrom a'vertical line, its tendency isto revolve the casing with itscontents.

The effect of the admission and discharge of fluid and the action ofgravity, caused by the removal of the center of gravity of the wholemass from a vertical line drawn through the axial shaft, is to cause acontinuous rotation of the casing and its contents, and the consequentrotation of the driving-pulley, attached to the shaft of the motor, andfrom which power is transmitted.

While this motor is intended to be actuated by an elastic fluid, thesame results can be effected by the employment of the force of anexplosive compound adapted to be ignited at the proper moment.

Having described our invention, we claim In a fluid-pressure motor, acasing or wheel mounted upon a tubular axis, and a tubular
